I also tried dbclient on x86 Ubuntu: works, too. I tried on x86 Ubuntu regular ssh client: it works. Interesting side note: if an unexpected option is specified (like -v), the error message WARNING: Ignoring unknown argument '-v' is displayed - even when put in background, so getting output from background processes generally works in my environment.
I wanted to put the ssh authentication to background, so the -f option is not a solution. The braces do not hurt, with and without its the same result. J Use program pipe rather than TCP connection
W (default 12288, larger may be faster, max 1MB) g Allow remote hosts to connect to forwarded ports y Always accept remote host key if unknown Is there a way to get the output either? What's the reason for this behaviour?įor convenience, here's the plain ssh help output (on my TomatoUSB): Dropbear client v0.52 (ssh -i /path/to/private_key 'sh -c "echo 1 echo 2 echo 3 uname -a"') &īy the way, I'm running the ssh client dropbear v0.52 in BusyBox v1.17.4 on Linux 2.4.37.10 (TomatoUSB build on a WRT54G). (ssh -i /path/to/private_key 'sh -c "echo 1 echo 2 echo 3 uname -a"')īut if an ampersand is concatenated to execute it in background, it seems to execute, but no output is printed, neither on stdout, nor on stderr, and even a redirection to a file (inside the braces) does not work.:
I'm trying to automate some things on remote Linux machines with bash scripting on Linux machine and have a working command (the braces are a relict from cmd concatenations):
